Jiangsu Suzhou PE Powder Dust-Free Pneumatic Conveying Project

Headpowder successfully completed the Jiangsu Suzhou PE Powder Dust-Free Pneumatic Conveying Project, delivering a tailored bulk material handling system for a local polymer processing facility. This case study outlines how the system resolved long-standing operational bottlenecks while maintaining strict environmental standards.

Project Background

A medium-sized manufacturer in Suzhou’s industrial zone required a reliable method to transfer polyethylene (PE) powder from storage silos to production lines. The existing manual and mechanical conveying methods led to frequent dust emissions, material waste, and elevated cleaning costs.

Customer Pain Points

The client faced three primary issues:

• Dust Contamination: Open transfer points released fine PE powder into the workshop air, posing health risks to operators and requiring extensive ventilation.
• Material Loss: Spillage during handling resulted in up to 3% material loss each month, directly affecting profit margins.
• Maintenance Downtime: Mechanical conveyors suffered from blockages and wear, causing unplanned stoppages that reduced overall production efficiency.

Solution Overview

Headpowder designed and installed a fully enclosed pneumatic conveying system specifically for PE powder. Key elements included:

• Closed-loop dilute phase conveying with baghouse filtration to capture all airborne particles.
• Automated PLC control with pressure sensors to optimize air-to-material ratio and prevent line blockages.
• Stainless steel piping with smooth internal surfaces to minimize friction and product degradation.

Operational Benefits

After commissioning, the system delivered measurable improvements:

• Dust emission levels dropped below 0.5 mg/m³, meeting local environmental regulations without additional air treatment.
• Material loss was reduced to less than 0.2%, saving approximately $12,000 annually.
• Unexpected downtime decreased by 85% thanks to the self-cleaning filter design and wear-resistant components.

This project demonstrates how Headpowder’s dust-free pneumatic conveying technology helps manufacturers achieve cleaner, more cost-effective powder transfer in demanding industrial environments.
